Most of the general cosmetics are in liquid, emulsion or paste form, and do not have a distinct appearance. It must express its own characteristics through beautiful and unique packaging design. Therefore, cosmetics generally rely on packaging to achieve good sales. Plastic and glass are currently the main cosmetic packaging container
materials, and among them, plastic is the most used.
As far as the current situation is concerned, due to the lightness and low price of plastic, it is easy to form large-scale production, and it can be made into bottles of various sizes, transparent, opaque and various colors, and the printing performance is very good. Thermal transfer, inkjet, printing and other methods directly print instructions, logos, and barcodes on the surface of the container. Therefore, plastic products have occupied more than 80% of the packaging market of cosmetics and become the most important packaging container for cosmetics.
In the past, cosmetics were generally packaged in glass bottles. However, due to the single variety of glass containers, even if there is a better design concept, due to technical and material limitations, it is often impossible to achieve. However, plastic materials have great advantages in this regard. They are not only rich in sources, but also have good molding properties. They can be manufactured into plastic containers such as bottles, cans, and boxes of various structures and shapes, and can be decorated and designed. Coupled with the rapid development of PET resin in cosmetic containers in recent years, it has led to a major change in replacing glass bottles with plastics.
